実験手順
To a solution of diphenylmethyl (S)-3-[(2S,3R,4R,5S)-2,3,4,6-tetrahydroxy-5-(L-leucyl)aminohexanoyl]amino-3-phenylpropionate (246 mg) in methanol (1 ml) was added 1N hydrochloric acid (0.396 ml) at room temperature. Concentration gave a residue, which was recrystallized from methanol-diethylether to afford the title compound (180 mg).
